SYNTHESIS AND CHARACTERIZATION OF MALEIC ROSIN MODIFIED ACRYLIC RESIN FOR PAPER-PLASTIC COMPOSITE ADHESIVE

摘要

In this paper, allyl maleated rosin ester was synthesized by the esterification of maleic rosin and allyl alcohol with catalyst. Then a new waterborne paper-plastic composite adhesive was prepared through the semi-continuous emulsion polymerization method with acrylics. The structure and properties of modified acylic resin were characterized by IR spectra, DSC and T-style peel strength test. This paper-plastic composite adhesive had good adhesive properties, longer stability period and low cost.
